Kim, Chicago, 11].,assignor to Container Corporation of America, Chicago, 11]., acorporation of Delaware Filed Aug. 9, 1965, Ser. No. 478,255 12 Claims.(Cl. 229-15) This invention relates to a partition formed of foldablepaperboard, and more particularly, to a partition having a base pad andseparator panels hinged to and upstanding from the base pad for definingfour horizontally spaced areas.

An object of this invention is to provide a paperboard partition havinga base pad of full transverse partition dimension and having two fullheight separator sections upstanding from the base pad and meetingmedially thereof to define four spaced areas on the base pad.

Another object of this invention is to define a partition of the typenoted in the previous object that is unusually stable and rigid whenerected but yet that requires a near minimum amount of paperboard.

These and other objects will be more fully appreciated after reviewingthe following specification including the accompanying drawings,wherein:

FIG. 1 is a perspective view of a first embodiment of the subjectpartition;

FIG. 2 is a plan view of a blank suitably cut and scored to form thepartition of FIG. 1;

FIGS. 3 and 4 are perspective and plan views, respectively, of thepartition of FIG. 1 shown in various stages of assembly;

FIG. 5 is a perspective view of a second embodiment of the subjectpartition;

FIG. 6 is a plan view of a blank suitably cut and scored to form thepartition of FIG. 5; and

FIG. 7 is a perspective view of the partition of FIG. 5 shown partiallyset up.

Two embodiments of the subject partition are shown in FIGS. 1 and 5.Each of the embodiments includes a base pad 10 and two verticallyupstanding sections 12 and 14 which meet approximately centrally of thebase pad to divide it into four areas. Edge panels extend upwardly fromthe base pad 10 along diametrically opposite side edges thereof, and aregenerally equal in size and extend parallel to the separator section 12.The edge panels are hinged to the base pad 10 and to the separatorsection 14. In the embodiment disclosed in FIG. 1, the edge panels andseparator section 12 extend transversely to the longer dimension of thebase pad; whereas in FIG. 5, the edge panels and separator panel 12extend longitudinally of the longer dimension of the base pad.

Referring now to FIGS. 2, 3, and 4 for a detailed description of thepartition of FIG. 1, blank 20 is seen to be :divided by two generallyparallel spaced lines 22 into a middle section and two spaced endsections. The endward portions of each line 22 are scored as at 24 todefine hinge areas between the middle and end sections, and the middleof each line is uninterruptedly cut as at 26 between and to the scoredareas 24 to separate the middle and end sections. The middle sectionbetween the spaced lines 22 defines the base pad 10, and is divided byan uninterrupted cut as at 28 extending normal to and connecting thecuts 26 at lines 22 to define two base panels 30 and 31.

The end sections are each divided by parallel spaced lines 32 which arescored as at 33, and which extend only between the blank edges and lines22 normal to the lines. The lines 32 are located approximatelyone-quarter way in from the adjacent blank edges to divide the endsections into two end panels 34 and 36 of equal size and a middle panel38 twice as large as the end panels. Each 3,327,919 Patented June 27,1967 juncture between base and end panels is further provided with aslot 40 extending outwardly from the scored area 33 and of Widthapproximately equal to, but slightly in excess of the thickness of thepaperboard blank.

The partition is set up by initially folding the end sections abouthinge areas 24 upwardly approximately from the middle section.Thereafter, the base panels 30 and 31, which are originally coplanar andparallel to one another, are deflected slightly vertically at the edgesadjacent cut 28 in the opposite directions to provide that the panelscan overlap one another (as shown in FIG. 3 or 4), and are then swung inopposite directions until the edge of base panel 31 abuts the hingedjuncture 24 between the base and end panels. Panel 31 is then fittedthrough slot 40 and base panels 30 are moved away from one another inline generally with the free edge defined by the cut 28 to slightlydeflect the portions 42 of end panels 34 and 36 over slots 40 to permitthe base panels to clear one another and become coplanar once again.

In the setup condition, base panels 30 and 31 are substantially coplanarand parallel to one another and the two separator sections substantiallydivide the base pad into four horizontally separated sections.Similarly, the separator sections extend perpendicular to one anotherand the one separator section 14 extends entirely across the base padbetween the opposite edge panels. The partition can be torn down ordisassembled by reversing the procedure noted above.

The embodiment disclosed in FIGS. 5, 6, and 7 diflers from thatpreviously disclosed in the manner in which it is formed. In thisembodiment, base pad 10 is comprised of two separate base panels 52 and54, and each separator section 12 and 14 is comprised of a single panel56 and 58, respectively.

To form the partition, rectangular blank 60 is divided by a first pairof spaced parallel lines 62 and 64, and by a second pair of spacedparallel lines 66 and 68 which extend normal to the first pair of linesand which trisect the blank. Line 62 of the first pair of lines extendsentirely across the blank and includes at its opposite ends outwardly oflines 66 and 68, spaced score areas 70 and 72, and which includes to andbetween the lines 66 a cut area 74. The second line 64 extends onlytwo-thirds across the blank and includes a cut area 76 between lines 66and 68, and a scored area 78 extending from line 68 to the adjacentblank edge. Line 66 of the second pair extends only outwardly of thefirst pair of lines, and includes a cut area 82 between and to cut 76and the adjacent blank edge, and a scored area 84 between cut area 74and the adjacent blank edge. Line 68 includes a cut area 86 extendingbetween and to cut areas 74 and 76 and a scored area 88 extendingbetween the cut area 74 and the adjacent blank edge. As such, the blankis divided into the base panels 52 and 54, the separator section panels56 and 58, and edge panels 90 and 92.

The partition is formed by initially lifting the edge panel 92, basepanel 54, and separator section panel 56 upwardly relative to theremaining base panel 52 and edge panel 90, with the separator sectionpanel 58 accommodating this movement by means of its hinged connections84 and 88 to the edge panels. Thereafter, the separator section panel 56and base panel 54 are folded in the same direction about their hingedconnections 78 and 72, and the edge panel 90 is folded about its hingedconnection 70. The separator section panels 56 and 58 have notches 96each open to the edge of the panel to receive one another (as shown inFIG. 7) for interfitting the panels together.

In the set-up condition, the base panels 52 and 54 are coplanar with oneanother and the separator section panels 56 and 58 cross one over thebase panels. The line 64 of the blank is located about one-sixth thelength of the blank from the adjacent blank edge, and the lines 62 and64 are spaced from one another the same one-sixth distance in thepreferred embodiment.

While two specific embodiments of the subject invention have beendisclosed, it will be obvious to those skilled in the art thatmodifications can be made therefrom without departing from the inventivedisclosure. Accordingly, it is desired that the subject invention belimited only by the scope of the claims hereinafter following.
